2.2.3 SERVICE PACKAGE SERVICE
2.2.3.1 General
The SLE-SM Service Package service is used to request new contacts or modify or delete
existing scheduled contacts.
There are seven Service Package operations that CM can perform when invoked by UM:
a) CREATE_SERVICE_PACKAGE (CSP)—to request CM to create a Service Package;
NOTE – Creation of a Service Package implies that resources to support all scenarios
contained within that package have been committed by the SLE Complex.
b) REPLACE_SERVICE_PACKAGE (RSP)—to replace parameters or references in an
existing Service Package at CM;
c) DELETE_SERVICE_PACKAGE (DSP)—to delete a Service Package that resides at
CM;
d) QUERY_SERVICE_PACKAGE (QSP)—to query the content of an existing Service
Package;
e) SELECT_ALTERNATE_SCENARIO (SAS)—to select an alternate Service Scenario
of an existing Service Package at CM to be the scenario to be used before or during
the execution of the Service Package;
f) APPLY_NEW_TRAJECTORY (ANT)—to apply a new Trajectory Prediction to an
existing Service Package at CM.
g) APPLY_NEW_SPACE_LINK_EVENTS_PROFILE (ANSLEP)—to apply a new
Space Link Events Profile to an existing Service Package at CM.
There are two Service Package operations that CM can perform autonomously and notify
UM:
a) SERVICE_PACKAGE_CANCELLED (SPC)—to cancel an existing Service Package
that is no longer supportable by the SLE Complex;
b) SERVICE_PACKAGE_MODIFIED (SPM)—to modify an existing Service Package
because of a change in conditions in the SLE Complex that makes the Service
Package supportable only if modifications are applied.
There is one Service Package operation that UM can perform when invoked by CM:
c) CONFIRM_TENTATIVE_SERVICE_PACKAGE (CTSP)—to confirm acceptance of
a Service Package proposed as a result of rule-based scheduling by CM. Proposing a
Service Package implies either (1) that resources to support the scenario contained
within that package have been committed by the SLE Complex, or (2) that such
